Description

  
   if (!key.numeric) {
      compareResult = compareBytes(first, start1, end1, second, start2, end2);
    }

those lines above, compare two byte arrays in a wrong way, it will cause an ArrayIndexOutOfBoundsException, that should be

  
   if (!key.numeric) {
      compareResult = compareBytes(first, start1, end1-start1, second, start2, end2-start2);
    }
